Problems solved by technology

Since the pump body of the variable capacity hydraulic oil pump is made of steel, it is only suitable for conveying oil. If the water is conveyed, when the pendulum rotor moves, it will rub against the steel pump body, which will cause wear and tear and cannot work normally.
Therefore, the existing variable capacity hydraulic oil pump cannot deliver water

Embodiment 1

[0034] Such as Figure 1 ~ Figure 4 As shown, the variable capacity multi-chamber hydraulic water pump includes a pump body 1, and a plurality of working chambers 103 are arranged in the pump body 1. In this embodiment, two working chambers are taken as an example, and each working chamber is corresponding to the pump body 1. The position 103 is respectively provided with an inlet 101 and an outlet, and the two outlets are combined into a total outlet 102 on the pump body 1 . The two adjacent working chambers 103 are spaced apart from each other. On the pump body 1, an eccentric shaft 5 is installed through a bearing along the centerline of the working chamber 103. The eccentric shaft 5 can be integrated or divided into multiple sections and connected by splines. , this embodiment takes the latter as an example. On the eccentric shaft 5, a pendulum rotor 3 is set inside the pump body 1. The number of the pendulum rotors 3 is the same as that of the working chamber 103, and th...

Embodiment 2

[0036] Such as Figure 5 As shown, the variable capacity multi-chamber hydraulic water pump includes a pump body 1, and a plurality of working chambers 103 are arranged in the pump body 1. In this embodiment, three working chambers are taken as an example, and there are three corresponding suspension rotors 3, eccentric The shaft 5 is divided into three sections and connected by splines. Others are with embodiment 1.

Embodiment 3

[0038] Such as Figure 6 As shown, there are two working chambers 103 in the pump body 1, the two working chambers 103 are separated by a partition, the eccentric shaft 5 is integrated, and the others are the same as in the first embodiment.

Abstract

The invention relates to a variable-volume type multi-chamber hydraulic water pump, wherein an eccentric shaft is arranged on a pump body and is provided with dangling rotors and a guide body in the pump body. The variable-volume type multi-chamber hydraulic water pump is characterized in that the dangling rotors have the same quantity with a plurality of working chambers and respectively positioned in the corresponding working chambers; the dangling rotors are distributed on the eccentric shaft in a staggered way and evenly distributed along the 360-degree circumference direction; a high-polymer composite material wear-resisting layer is attached on the inner surface of the pump body or the outer surface of each dangling rotor; the dangling rotors are in interference fit with the pump body; compensating plates are arranged at two sides of each working chamber in the pump body; and the volumes of the corresponding working chambers simultaneously are changed to drain water away to formthe variable-volume type multi-chamber water pump, thereby realizing the function of one machine with a plurality of pumps. The invention has the advantages of high total head, large water discharge amount, high output efficiency, remarkable energy-saving effect, long service life, small size, light weight and wide application range.

Description

technical field [0001] The invention relates to a variable capacity multi-cavity hydraulic water pump. Background technique [0002] Traditional water pumps have always been dominated by centrifugal pumps, which have a complex structure and are used in general occasions, with short delivery distances, small displacement, and low efficiency. The higher head uses multi-stage pumps, the highest head is 300 meters, and the average output efficiency is below 30%. If it is used in a mine with a depth of 1,000 meters, four pumps must be connected in series, that is, high-power multi-stage pumps must be used, and four stepped pools must be equipped at the same time. Complete the task of delivering water. The variable displacement hydraulic oil pump is composed of a pump body, an eccentric shaft installed along the center line of the pump body, a pendulum rotor mounted on the eccentric shaft inside the pump body, and a guide body installed on the upper part of the working chamber of...
